Terror in the Crypt (Italian title: La cripta e l’incubo) is a 1964 Italian-Spanish horror film directed by Camillo Mastrocinque.

The screenplay was by Tonino Valerii and Ernesto Gastaldi, based on the 1872 novel Carmilla by Joseph Sheridan Le Fanu.

[2] It was the third film adaptation of the novel, following Carl Theodor Dreyer's Vampyr (1932) and Roger Vadim's Blood and Roses (1960).

Mastrocinque was more prominently known for his comedy films, and was suggested by agent Liliana Biancini in order to help find the director new work.

[5] In a contemporary review The Monthly Film Bulletin wrote: "This is occasionally quite atmospheric, with an effective climax and some nice shots of the castle battlements by moonlight and so forth.
